Question

Bohr versus Schrodinger. Compare and contrast the Bohr model and the Schrodinger model for hydrogen. What are the ways that they are the same and the ways that there are different? 

Answer 1

Differences:

1) In the Bohr Model, the electron is treated as a particle in fixed orbits around the nucleus.But In the Schrodinger quantum Mechanical Model, the electron is treated mathematically as a wave nature properties. The electron has properties of both particles and waves.

2) In Bohr model particle considered as one-dimensionl model, which was is described by "n" the principle quntum number.But In the Schrodinger quantum Mechanical Model the electron ocuppy 3-Dimensional space model.

3)Bohr model have 4 quantum state while Shrodinger model work with 3 quantum states

4) Schrodinger model calculates the angular momentum correctly and shows the angular momentum degeneracy of energy states.But it is hard to find with Bohr model.

5)The Schrodinger equation doesn't give a mean radius or radius expectation value that is the same as the Bohr model radius.

Similarity:

1) Electrons are outside the nucleus, while protons and neutrons are in the nucleus.

2) Electrons in lower energy levels are closer to the nucleus than those occupying higher energy levels.

3) Electrons can move to higher unoccupied energy levels if sufficient energy is gained.

4)The potential energy function is the same for both.

5) The energy level solutions are the same for both.
